Description

  The present invention relates to a skimming prevention device, and more particularly, to a skimming prevention device used as a sheet or card case that can prevent skimming of data recorded on an IC card such as a cash card.

In recent years, counterfeit IC cards, such as cash cards, SUICA (trade names), ID cards, and other data recorded on IC cards, have been skimmed and copied, and used instead of the real ones. The damage is increasing.
An IC card such as a cash card is often stored in a wallet or a card case, and is stored in a clothing or bag such as a jacket or carried.

On the other hand, the skimming device is configured to read data from an IC card in a non-contact manner by transmitting electromagnetic waves toward the IC card such as the cash card.
Therefore, the person who performs skimming can easily skimm data without being noticed by the card holder by operating the reader of the skimming device by approaching the card holder.

In order to prevent this skimming, for example, Japanese Patent Laid-Open No. 63-92498 uses interior materials whose front and back surfaces are metal-processed (copper sulfide), and Japanese Patent Laid-Open No. 9-269985 uses a metal such as copper that blocks magnetism. A structure constituted by a foil is known. There is also a structure in which a metal plate is built.
However, the structure incorporating a metal foil or metal plate has drawbacks such as being unable to bend and folding the wallet in half.
In addition, when using a cloth material, metal processing is difficult, and it is necessary to overlap the front and back and sew the edges, which is troublesome, and printing on the surface cannot be performed, resulting in lack of decorativeness. It was.
